a) Are you saying that the dispersion issue was because the low barrel life gradually degraded the performance?

It may have been a factor, but I don't think it was the major cause for the phenomenon.

 

B) The Mark 7 fired an AP shell Mark 8 at a muzzle velocity that at average was around 740 mps, roughly 760 at most.

Firing the HC Mark 17, the muzzle velocity went up to 800 mps, 820 at most.

 

And the Italian gun had that range with a maximum elevation of 36°. During trials, a gun at 45° fired an AP shell at 46'280 m, and an HE one at 48'270.

 

>dispersion issue

Barrel life,while also being a factor, actually degraded performance only after shooting barrel fully(and not swapping liners before next engagement)

So no, just small project misconception

Sorry, I thought you were referring to the American Mark 7 gun; I had not read carefully.

 

Anyway, the Soviet 406 mm gun gives an idea, but its results were uneven. In some respects, the Soviet industrial base was not up to the task.

Also, my point stands, that the Italian gun had excellent range even though its maximum elevation was rather small.

 

It's interesting to note that the idea of equipping the new Italian battleships with 381 mm, instead of going to the 406 mm limit, was followed through because going for the biggest caliber would have meant longer times and bigger costs; also, the Italian industry already had experience with the 15-inch, as it had built the guns for the never completed Francesco Caracciolo-class battleships.

Also, the Italian top brass' opinion was that the Model 1934 was good enough to be a match for 406 mm guns; so, it would have been sufficient even against the Lion-class, if they had made an appearance in the Mediterranean. And they also thought that it was superior to the 14-inch Mark 7 of the King George V-class.

FYI, Soviet industry managed all 406mm guns production/maint with no sweat. On the other hand, 130mm, 37mm and ships is another(and very sadly in some parts) matter.

I may have exaggerated-

However, on NavWeaps it says that the results were uneven also because of the poor quality of the shells and the propellant. And the Italian example shows that building guns is by itself no guarantee that they'll perform as well as they could.

>NavWeaps

:D

Results were uneven,yes, but in... '39. In '40 (after some quality control) dispersion was fixed down to planned level.

Love this discussion.

 

Oh, Historynerd- above, I was making a joke, not actual commentary on the weapon. ;)

 

Oh, sorry. I hadn't understood.

Very well, if you say so, I have no reason to believe otherwise.

Just found this today. No sound but very interesting to find archive film. Covers multiple ships including Ark Royal, Nelson, and shows bits of sailor training

 

 

I also found this German film that includes the Ark Royal (though it's more likely the Furious or Courageous) and Stukas dive bombing

Just in time for a certain Interview, which I believe is to be published shortly!

 

I was gonna ask in the general questions if you guys have a set time to publish the interviews so I don't have to keep refreshing the kickstarter page every 5 minutes XP

W99;

 

No, not set times- just usually on Fridays. :)

 

The Barham explosion is well known, and what's even more unfortunate is the large group of sailors still on the hull prior to the explosion. ;(

It's surreal watching it, as you can see the sailors on the hull trying to jump off before she exploded.

 

If it's something that can be mentioned, is there a chance that she will enter VB at some point?

While looking up anything on Fire Control to help Nel, I came across this:

 

 

It's so entertaining for me to see all these mechanics in work

I was doing research for... something that will be revealed soon. I found these two instructional videos on american fire-control computers.

 

 

 

 

 

 

 

Enjoy.

Found this about the US Coast Guard during WW2. The Coast Guard has actually been in the war since '39. :)

That is really neat- unrelated to anything, I'm looking forward to the HBO series Mighty Eighth...if that ever comes out. :)
